The first post: No, Nay, Never replace with "some old caps".
At first, try to determine WHY the caps failed. E.G. Is there something exceedingly hot around, and can you fix it?
Second, the best thing to do is take caps with higher Voltage rating, because many manufacturers cut the margin exceedingly close, resulting in premature failiure.
Third, due to the heat in the Power supply, rather take Aluminum-Caps, not Tantalum caps. They have the tendency to start burning.
Fourth, look at how the caps are arranged. When there are some in Parallel, take normal ones. Else, you must take Low-ESR ones.
- kps 10y ago> At first, try to determine WHY the caps failed. In current consumer gear, 99% of the time the caps failed because they are garbage that comes nowhere near to meeting their supposed specification, in designs where the specifications are already cut to the absolute minimum. In sufficiently old gear, they failed because they were sitting idle too long, and can probably be reformed.
- nasalgoat 10y agoI repair old pinball machines for fun and you pretty much need to replace every capacitor in them due to age - anything over 5-10 years old, even if working, is a time bomb waiting to go off.
